MECHANISM FORDISCHARGING COAL, & INTO ONE OR A SERIES OF BINS.

SPECIFICATION forming part of Letters Patent No. 247,779, dated October 4, 1881.

Application filed August 1, 1881.

To all whom it may concern:

Be it known that I, SAMUEL A. PIPER, of Newton Upper Falls, of the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Mechanism for Discharging Goal or various other Matters into One or a Series of Bins; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view; Fig. 2, a front elevation; Fig. 3, a longitudinal section, and Fig. 4 a transverse section of two coal-bins and their coal discharging mechanism in accordance with my invention, the nature of which is defined by the claim hereinafter rendered.

The object of the invention is to prevent the usual breakage and waste that result from the ordinary way of discharging coal from a wheelbarrow or car into a bin, the coal under such circumstances being usually dumped from a position several feet above the place of its reception, and in consequence of falling and impinging on the bottom of the bin or other coal therein becoming'more or less broken and powdered.

In the drawings, A A exhibit two of a series of coal bins, having at their upper parts a railway, B, extending across both of them, and on such railway a car or wheel-carriage, O, to run from over one to and over the other of such bins, as occasion may require.

Within the car and extending down from it,

as represented, is a hopper, D, provided with a telescope chute or conductor, E, consisting of a series of tubes, at l) c d, the first of which extends down from the hopper and into the tube 1), which in turn extends within the tube 0, and the latter into the tube d, the several tubes being provided at their ends with stops or shoulders, as shown at e, f, and 9, arranged so that on the tube dbeing drawn upward the tubes 0 and b will be successively raised upward relatively to the tube a,the tubes being applied to each other as those of a telescope are usually made and applied.

By means of ropes g g the lower tube, d, is connected with a Windlass, F, the journals of whose shaft 76 are supported in boxes h, fixed to two standards, it, erected on the car-platform.

(N0 model.)

The said shaft 75 has fixed on it a gear, I, that engages with a pinion, m, fastened on another shaft, a, the latter shaft being provided with a crank, 0, and a ratchet-wheel, p.

The shaft n is supported in suitable boxes, q 1, one of which is fastened to one of the standards i and the other to the top of an auxiliary standard, 8, arranged as represented. A lever-pawl, t, pivoted to the standard 8, engages with the ratchet-wheel p.

If we suppose the car with its hopper to be directly over one of the bins, and the telescopeconductor to be extended so that its lowermost tube may rest on the bottom of the bin, the mechanism will be ready for receiving coal and dumping it into the bin. On the conductor being supplied the coal therefrom into the hopper, and the lower tube being drawn up a little by the Windlass, the coal will flow out ofit and into the bin. As the charge in the bin may increasein height, the lower tube of the conductor is to be intermittently elevated by means of the Windlass, the ratchet and pawl serving to maintain the conductor at any desirable elevation within the bin. On the tube 61 rising upward to the top of the tube 0 the said tube 0 will be caused to move upward during the further elevation of the tube 61. 'When all the tubes, 1) c (l, are raised, so as to surround the tube a, and the Windlass is kept in revolution, the hopper and the jointed or telescoped conductor will be elevated above the partition to, between the bins, in order for the carriage with its hopper and the telescope-conductor to be moved upon the railway to and over the next bin for the purpose of aiding in supplying it with coal.

From the above it will be seen that the coal simply flows out of the conductor at its foot, such conductor being kept full in the meantime by the hopper, into which the coal is to bedischarged. Consequentlylittleornobreakage of the coal, comparatively speaking, can follow when my invention is used for supplying a bin.

There may be any greater number of bins, the railway being arranged to extend across them.

I do not claim a telescopic tube and devices for extending and contracting it lengthwise,

and admittingoi it being inclined more or less carriage, all being arranged substantially and laterally. for use as specified.

I claim-- The combination of a series of bins, with a, SAMUEL PIPER 5 railway and a carriage therefor, and with a hop- Witnesses:

per, and a telescopic conductor, and mechanism R. H. EDDY,

for operating it, as described, applied to such S. N. PIPER.
